Optical nonlinear conversion processes are ubiquitously applied to scientific as well as
industrial tasks. In particular, nonlinear processes are employed to generate radiation in …

The possibility to manage and control spectral and spatial properties of optical-terahertz
nonclassical fields generated in strongly nondegenerate parametric down-conversion is …

Frequency-angular characteristics of signal and idler photons generated under spontaneous
parametric down-conversion are studied in a strongly frequency nondegenerate regime …

We study conditions for the generation of strongly correlated photons of two extremely
different frequency ranges, optical and terahertz, via the spontaneous parametric down …

Frequency-angular distributions of optical signals generated via spontaneous parametric
downconversion with the Stokes idler frequency shifts 0.2–5 THz are studied simultaneously …

In this study, we demonstrate the capabilities of the pulse train excitation approach in
determining key material properties of nonlinear crystals, such as refractive index, thermo …

Statistical distributions of the analog readings of an antenna-coupled THz superconducting
bolometer were measured and analyzed under a special type of irradiation by low-energy …

We study a calibration scheme for terahertz wave nonlinear-optical detectors based on
spontaneous parametric down-conversion. Contrary to the usual low wavelength pump in …

We study parametric down-conversion (PDC) of optical laser radiation in the strongly
